Just because you start a thread, doesn't mean you own it (or get to control the life it takes on). If you don't want unsolicited feedback on a subject, don't start a discussion about that subject on
a public forum
You can't have your cake and eat it to. There's nothing more obnoxious and juvenile than members who start complaining that someone is giving them feedback they don't like. This usually happens in sales threads, where someone posts something for twice what it's worth, and then gets pissy when the forum points it out and "kills their sale" (
proper interpretation: helps less informed members avoid getting taken advantage of). The same phenomena occasionally comes up outside of sales threads, as it has here, and it's just as inappropriate when it does.
If you post a thread, people will comment. Learn how to appropriately deal with criticism. That's a big part of growing up.
